Hey everyone, I’m diving into the world of UART communication to enhance my smart TV setup! I’ve been struggling with controlling my Sharp Interactive Whiteboard via LAN, so I decided to try a different approach. I connected an ESP8266 to the TV’s serial port, and now I have one-way control. But here’s the catch—I want to get feedback on the TV’s current state, like whether it’s on or off, or which input it’s using.
I’ve set up the UART configuration with specific data commands for power and input control. For example, sending 0x50, 0x4F, 0x57, 0x52, 0x20, 0x20, 0x20, 0x31, 0x0D, 0x0A turns the TV on. But I’m curious—can I use UART to check the TV’s response or use it as a sensor? I’ve scoured the ESPHome docs, but I’m not finding clear guidance on this.
If anyone has experience with UART feedback or knows how to configure it for sensor-like functionality, I’d love to hear your insights! Maybe there’s a way to log the TV’s responses or trigger actions based on its state. This could really take my setup to the next level. Thanks in advance for any help!
